Benefits of technology

[0011]Such sound processors and methods are advantageous for a variety of reasons. For example, the present inventors have determined that continuously supplying power to the electrical contacts can increase the likelihood of contact corrosion in those instances where the contacts may be exposed to corrosive substances (e.g., water, salts and certain chemicals). The power supplies electromotive force that drives co

Problems solved by technology

Sound processors can include various control structures (e.g. a volume knob and/or a program selector switch) tha

Embodiment Construction

[0045]The following is a detailed description of the best presently known modes of carrying out the inventions. This description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the inventions.

[0046]The present inventions have application in a wide variety of systems that provide sound (i.e. either sound or a perception of sound) to the hearing impaired as well as others who require such systems on a situational basis. One example of such a system is an ICS system where an external body worn sound processor communicates with a cochlear implant and, accordingly, the present inventions are discussed in the context of such ICS systems. The present inventions are not, however, limited to ICS systems and may be used in combination with other systems for the hearing impaired that currently exist, or are yet to be developed. Nor are the present inventions limited to ICS systems with body worn sound processors. The present ...

Abstract

Sound processors and systems including sound processors are disclosed.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation-in-part of U.S. application Ser. No. 12 / 568,851, filed Sep. 29, 2009, which claims benefit of U.S. Prov. App. Ser. No. 61 / 102,726, filed Oct. 3, 2008.BACKGROUND[0002]1. Field[0003]The present disclosure relates generally to sound processors such as, for example, the sound processors in implantable cochlear stimulation (or “ICS”) systems.[0004]2. Description of the Related Art[0005]ICS systems are used to help the profoundly deaf perceive a sensation of sound by directly exciting the intact auditory nerve with controlled impulses of electrical current. Ambient sound pressure waves are picked up by an externally worn microphone and converted to electrical signals. The electrical signals, in turn, are processed by a sound processor, converted to a pulse sequence having varying pulse widths and / or amplitudes, and transmitted to an implanted receiver circuit of the ICS system. The implanted receiver circuit i...
